[Influence of fish oil on serum lipoprotein level in endogenous hypertriglyceridemia]

The influence of fish oil on the level and composition of lipoprotein fractions in hypertriglyceridemic men was evaluated. The observation was performed in 2 groups of patients, 10 cases each (a cross-over study). In the group I subjects received fish oil first, in the dose of 12 grams daily (3.6 g of EPA and DHA) for 3 weeks, and then, for the next 3 weeks, olive oil in the same dose. Patients from the group II received the same oil but in the inverse order. Results after olive oil were a control for fish oil. Marked decreases in the serum and VLDL triglycerides and also VLDL-cholesterol level after fish oil was shown. Increases in LDL and HDL cholesterol were observed. In 9 patients fish oil was given for 6 weeks. No differences in the serum lipid levels after this period of time in comparison with results after 3 weeks were observed.
